上海市区学龄前儿童屈光异常852例分析

Investigation of the abnormal refractive state in 852 preschool children of some Shanghai districts

目的:了解上海市区部分学龄前儿童屈光的异常状态及视力矫正情况。方法:视力异常学龄前儿童852例(1615眼)作散瞳验光检查,并对检查结果进行分析探讨。结果:单纯近视443眼(27.43%),复性近视散光255眼(15.79%),单纯远视287眼(17.77%),复性远视散光347眼(21.49%),混合性散光283眼(17.52%)。随着年龄的增长,就诊的学龄前近视患者逐渐增多;父母近视对学龄前儿童近视发生率的增加有影响;屈光不正大都以轻中度为主(82.43%),视力大多(80.40%)是可以矫正的。结论:学龄前儿童近视和近视散光的发生率有明显增加的趋势。

AIM： To investigate the abnormal refractive state and vision correction in preschool children of some Shanghai districts. METHODS： The ocular refraction status of 1 615 eyes in 852 preschool children with visual problems were checked by retinoscopy in dilated pupil after being used atropine eye drop. RESULTS： There were 443 eyes with simple myopia accounting for 27.43%, 255 eyes with compound myopia astigmatism accounting for 15.79%, 287 eyes with simple hyperopia accounting for 17. 77%, 347 eyes with compound hyperopia astigmatism accounting for 21.49%, and 283 eyes with mixed astigmatism accounting for 17.52%. The number of preschool children with myopia who visited hospital gradually increased with age. The parents with myopia would influence the incidence of myopia for preschool children. Mostly, the ametropia in these preschool children were mild or moderate （82.43%） and the error of refraction could be corrected （80.40%）. CONCLUSION： The incidence of myopia and myopic astigmatism in preschool children has significant increasing tendency.
